I know someone living there for 8 years, got rejected 2 times for PR. He is retrying again. If he get rejected, he is planning to move to another country. Actually many left because of that. He told me Ethnicity quota is harsh. Unfortunately, he is European. He feels enraged when he sees chinese mainland or malay chinese or indo chinese get PR just after 2 years... But I understand Singapore, such a small island, they must limit immigration.
